Doepfer

I've been picking up modules here and there (some of them from this board) to build my first modular system.  I don't really know what I'm doing, but I've been reading through the manufacturer descriptions as I scope out pieces.  

Right now I have collected:
a111 VCO
a120 VCF
a131 VCA
a141 VCASDR
a147 VCLFO

I think this is enough for the unit to make noise.  Provided, of course, that I pick up a case/power and patch cable set.

I am also wondering if I can use the gate triggers off my tr-606 to sequence monotone patterns on this setup.  

Advice on anything I might be missing or using the tr-606 would be appreciated.

Thanks!
